force_tz {lubridate} | R Documentation |
force_tz returns a the date-time that has the same clock time as x in the new
time zone.
Although the new date-time has the same clock time (e.g. the
same values in the year, month, days, etc. elements) it is a
different moment of time than the input date-time. force_tz defaults to the
Universal Coordinated time zone (UTC) when an unrecognized time zone is
inputted. See Sys.timezone
for more information on how R
recognizes time zones.
